Detail The CCD black scan level is abnormal when
the shading.
Cause Improper connection of the CCD unit flat
cable
CCD unit abnormality
MCU PWB abnormality
Check
and
remedy
Check connection of the CCD unit flat cable.
Check the CCD unit.
11 Content Shading trouble (White correction)
Detail The CCD white scan level is abnormal when
the shading.
Cause Improper connection of the CCD unit flat
cable
Dirt on the mirror, the lens, and the reference
white plate

CCD unit abnormality
MCU PWB abnormality
(When occurred in the SPF/RSPF scan
position.)
Improper installation of the mirror unit
Check
and
remedy
Clean the mirror, lens, and the reference
white plate.
Check the light quantity and lighting status of
the copy lamp (SIM 05-03).
Check the MCU PWB.
